The Nady GEQ 131 1-Channel Graphic Equalizer features 31 and a 1/3rd octave bands for a single channel. It fits in a 19" rack space and only takes up one slot. The equalizer is equipped with balanced XLR and 1/4" TRS inputs. It has XLR and 1/4" TRS outputs as well. The unit uses ultra-low noise circuitry, as well as a parallel filter design to minimize phase distortion. It features a low-cut filter at 40Hz, a band range of ±12dB gain and an EQ On/Off bypass switch with a status LED. For added convenience, there's also a gain status LED bar graph with peak LED indicator and a power LED. The power supply can support worldwide voltage regulations and the chassis is constructed of durable steel.

You can use it for tuning a room with the help of audio reinforcement system. It also works well with amplifiers and instruments. You can take advantage of the low-cut feature or use it with your guitar to modify the sound of the instrument. You can brighten the sound, add body to a thin sounding guitar, or even give the instrument's sound a totally different character. A graphic EQ is a useful tool in the studio as well. You can fix tracks where the sound is a little off or shape the sound of a track by changing the frequency response. You can even create artificial stereo by splitting a signal, equalizing the split signals differently and then use panning.
